PAPER .RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 367,297, dated July 26, 1887. Application filed December 18,1886. Serial No. 221,935. (No model.)

To all whom it may concern:

Be it known that I, OLIVER H.HIOKS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illi-. nois, have invented a certain new and useful Improvement in Paper Receptacles; and I hereby declare the following to be a full, clear, and exact description of the same.

In paper receptacles for carrying merchandisc of a more or less liquid nature, and formed by folding sheets of paper, the corners of the base are unavoidably weakened by the folding, owing to'bending and straining, and, sometimes, even breaking of the fiber, and naturally are the first to yield to the action of the moisture, thereby greatly diminishing the durability of the receptacle. It also appears that the corners formed in the folding, and, as aforesaid, most liable to yield to the effect of the moist contents, have to withstand the greatest strain. It is my object to overcome this difficulty by applying to the r, folded corners of paper receptacles of this description a water-proof substance, which will not only render those parts impervious to moisture, hut, and' particularly, strengthen the receptacle, and at the same time not add materially to the cost of manufacture.

To this end my invention consists in the new article of'manufacture comprising a re ceptacle formed by folding paper more or less pervious to' moisture and re'enforced and renderedimpervions to moisture at the corners of the base.

In the drawings, Figure 1 represents a sheet of paper suitably shaped and creased to form, when folded, the receptacle shown in Fig. 2, and having paraffine applied at the parts thereafter, to constitutethe corners of' the base; and Fig. 2a paper receptacle for liquids formed by folding the sheet illustrated in Fig. 1 and containing my improvement.

While I obtain the" best results by the use of paraffine in producing my improved ar ticle, and the present description is confined to the same, other substances can be used which may be readily and similarly applied for the purpose-for example, wax, paint, varnish,-and the like.

A is the sheet of paper,- scored for folding, as illustrated by dotted lines, in a manner to form, when folded, the receptacle B, Fig. 2.

At the points 8 upon the sheet A, -which,when the folds are-made, constitute the lower four corners of the receptacle, I apply, preferably, but not necessarily, before the folding operation, paraffine in any suitable manner. As the corners s, owing to bending and straining of the fiber by the folding, are the weak points of the receptacle and the first to give way under the action and Weight of its liquid contents, it is not usually necessary to strengthen any other part of the receptacle, and I do not extendthe scope of my invention beyond reenforcing the corners, as described. However, by applying paraffine in strips up the inner sides, as shown at r, and especially to cover the points where the bail q and clamps p arefa-stened upon them, the receptacle may be additionally re-enforced, whereby it is rendered capable of retaining its shape when the inner walls, elsewhere devoid of paraffine, become saturated by the action of the liquid contents.

My improvement obviously enables receptacles of the class referred to to be made of much lighter paper than has hitherto been employed in their manufacture, since it is only necessary to'render them'durable th roughout all their parts for a sufficient length .of time to carry out the purpose for which they are used, and thus whatever extra expense is involved by the use of myimprovement would be more than counterbalanced by a consequent saving in paper.

\Vhat I claim as new, by Letters Patent, is 1. As a new article of manufacture, a re and desire to secure 'ceptacle, B, of folded paper more .or less pervious to moisture, having abase having folded corners .9, re enforced and rendered impervious to moisture, substantially as and for the purpose set forth. I

2. As a new article of manufacture, a receptacle, B, of folded paper more or less pervious to moisture, having a base having folded corners s, weakened by folding, re-enforced and saturated with paraffine, substantially as and for the purpose set forth.
